This invention appertains to. a mold for manuacturing articlesmade from concrete and has for anV object to provide' one especially designediand constructed for` the manufacture of` concrete weights for iron pipelines and for the substi` tutionl ofthe same for the more expensive cast ironlweights presently in-common use to weight down those portionsrof pipe lineslaid on the beds of'bodies of: water, such; as rivers and the like.

Another object of the invention hasv to-do with the provision of a mold of this kind, which has the advantage in'that it can be readily installedi at. a, point convenient. to the place of laying a pipe,v lineon-the bedl of a body of water, for the comparatively quick manufacture and application of therconcretei weights, thus avoiding the use of the more costly cast iron weights and the expense of transporting them from more distant pointsof production, n

' A furthen object of the invention: lies in' the provision lof the mold as hereinbefore specified and whichv embodies certain structural features that permit of the production of a concrete weight iny two complemental sections and provide means to allow for the fastening of the sections together and inplace ony a pipeline, thecompleted sections being made from a quick setting concrete thatis water resistantv and of greatstrength and-durability, Yetanother object of theinvention is to provide thefrnold with a novely and eflicient 'arrangernent off channels and passages for'the steam heatingI of the concrete mix during the setting period, in order]to quicken the set and to assure of" the weight sections having a uniformly compact, hard andfne textured finish when ready for removalfrom thernold; n

A' still f urtherobject of the invention is 'to rriake the rnold body into two identical sections toihefremovably clamped in place on a supporting pallet that is. carried by ay hollow core structure which divides the interior of the body into two fortlr in the `anpended claimsI and illustrated the accompanying drawingsirr which: n

Figure V14:` is a view of a section of a pipa show-` ingjthe manner of cutting the same toform a bolt receiving lug mol-ding element, the;` mode of the use of which being exemplili'ed in' Figures 6g '7 and 8. `f Reierring'to the. drawings in detail",y wherein like characters, of reference denotecorresponding parts throughout the 'several' views,` the invention, as it is exemplmed tneremiscomnnsed in a base structurel, oripallletomade up of a hottorplate i @,prefereply theform `uffa disk of comparaithe weights tively heavy gauge metal, whichis disposed concentrically of and welded to an annular member I2, preferably in the form of a flat metal ring.

Removably supported on the pallet is the mold body, in the form of a casing or jacket made in two semi-cylindrical sections I4a and I4b, each having its top edge inwardly angled to bevel the top end edges of the molded weight parts or sections W1 and W2, as at W3, as best shown in Figure 10. When positioned on the pallet, the bottom edges of the body sections I4a, I4b, rest on the annular member I2 and closely hug the edge of the bottom plate I0.

Rising from the center of the bottom plate Ill, of the pallet, is a hollow core I6, which is substantially cylindrical in form and has its bottom edge welded to the plate. Extending radially from opposite sides of the core I6 are hollow partitions or wings, each of which is comprised in a pair of spaced walls I8a and Ib that also have theirfbottom edges welded to the plate I6 and the space between the same closed, at the outer edge portions thereof, by ak vertical bar 20, preferably made from relatively heavy metal stock, square in cross-section, and between their top end edges by a strip of sheet metal 22, of substantially the same gauge as that from which the walls are made. Disposed horizontally within the space between the walls I8a and I 8b of one of the partitions only, is a strip of metal 24,l of the same gauge as that of the strip 22, to form an inlet passage 2B between the same and the bottom plate l0, of the pallet; `the passage opening outwardly through the adjacent vertical edges of the body sections |411, I4b, when the latter are in place on the pallet, for the intake of a fluid heating medium, Y preferably steam.

The bar 26, of the one partition, has its upper end terminating short of the top closure strip or wall 22 and its lower end welded to the outer end of the bottom strip or wall 24, while in the opposite partition, the bar 26 likewise terminates short of the top closure strip or wall 22 but has its lower end welded direct to the bottom plate I0, of the pallet. The outer ends of eachof the strips or walls 22 are downturned and weldedto the Yupper ends of the vertical bars 2U, butA are vented, as at 22a, to provide outlets for the aforesaid heating medium, the latter passing from the inner end of the inlet passage 26 into the interior of the core I6, through an aperture 26a in the core wall. v

The top endoi the core I6 is closed by a wall I6a and supports a suspension bail 28 which has its endsprojecting downwardly through the end wall IBa for welding to the side wall of the core. spaced one above the other within the core I6 are at least'two baffle plates 3,0 which are perforated adjacent their margins to permit of the upow of the heating medium therethrough; the .side wall of the core I6 being perforated below the lower of the bailles and similarly above the upper- :most baffle to permit the heating medium to enter the otherwise closed spaces within the partitions, the heating medium passing outwardly through lthe vents 22a at the top ends of the partitions. 4Asbest shown in Figure 4, the bail 28 is prefer- ;ably formed of a length of metal tubing, or pipe, Awith its ends within the core I6 open to evacuate :a portion of the heating medium; an outlet vent 28a being provided at the bend of the bail exte- :riorly of the core.

The body sections Illa, I4b, are secured in place ron the pallet in a manner that the outer sides of the `partitions span the joints between the adjacent edges of the sections; the securing means taking the form of at least three bands, each comprising two identical sections 32a, and 32h, preferably made from steel channel bars bent to semi-circular form, with the channels outwardly directed. Welded in the channel of each of the band sections 32a, 32h, adjacent each of the ends thereof, is a substantially U-shaped lug 34, to receive a clamp b'olt 36 (Figures 4, 11 and 13) the bolt also spanning the joint between adjacent edges of the body sections.

For the purpose of increasing the more or less tortuous path of flow of the heating medium through the upper portion of the core structure, a modied form of the latter to such end is shown in Figure 5 and, here, radially directed passages 40 are provided in the upper ends of the two partitions, by welding a strip 38, of the sheet metal, within the interior of each of the same; each strip being disposed in the plane of the top ends of the vertical bars 20, forming the outer vertical sides of the partitions, and is perforated adjacent its inner and outer ends for the up-flow of the heating medium through the perforations and into the passages for subsequent discharge outwardly of the vents 22a.

In order to provide means by which the molded weight sections W1, W2,`are to be vsecured in place on the pipe line A, companion apertured lugs W4 are molded thereon, simultaneously with the molding oi the sections themselves, to receive bolts W5 after the manner shown in Figures l, 9 and l0. For the purpose, a pair of lug forming elements 44 is mounted on the outer sides of the opposite walls I8a, IBb, of each of the core partitions or wings, adjacent the outer vertical side edges thereof, substantially as shown in Figures 6, 7 and 8. Each of these elements 44 is constituted in a part cut from va length of pipe 42, of a suitable diameter, somewhat after the manner shown vin Figure 14; one lineof cut being made crosswise of the pipe and the second y-y diagonally thereof,` the latter cut having "a semi-circular curvature to conform to that of the body sections I4a, I4b.

To mount these elements 44 in place on each of the opposite sides of th'e lcore partitions or wings, the crosswise cut end of each of the same is closed by a centrally apertured wall 44a, welded thereto, for engagement over a similarly apertured lug 46, welded on the inner side of a body section I4a, I4b, adjacent a vertical edge thereof; four of the elements and mounting lugs being employed for each half section of the mold, with two spaced apart, one toward the upper and the other toward the lower ends of the same; the elements 44 mounted on one partition or wing being disposed in line with those mounted on the other partition or wing. Each of the elements 44 is secured `to a lug 46 by means of a screw 48, threaded into a tapered boss 50, weldedon the adjacent side wall I8a, I8b, of the core partitions or wings, substantially as shown in Figure 6'; apertures 52 being provided in the wallof each' of the body sections I4a, I4b, one in linewith each of the lugsl 46, for thefinsertion of .a screw 48 therethrough and through the aligned apertures in the end wall 44a, of an element 44, and a lug 46, andinto engagement with a boss 50.

To facilitate the handling of each of the weight sections W1, W2, during and after the removal of the same from the mold, a carrying bail 54 is provided in the center of the rounded sides thereof, the ends of the bail being angularly bent. and embedded in the concrete during the molding oi 5 said sections, while the bent intermediate portion projects outwardly through a slot 56, formed in the wall of each of the body sections 14a, Mb, substantially as shown in Figure l2.

In the assembly and use of the mold, as thus constructed, the body sections |4a, 14h, will be positioned on the pallet in the manner before stated and secured by the clamp bands 32a, 32h, the adjacent ends of which are drawn together by the bolts 36 engaged with th'e lugs 34. Following this, the elements 44 are secured to the lugs 46 and the bosses 50 by the screws 48, the curved edges of the elements closely hugging the inner sides of the body sections, substantially as sh'own in Figure 6, and the mold is ready for the pouring of the concrete inwardly of its top end, to either side of the core I6 and its partitions or wings. A heating medium supply connection (not shown) will be made with the inlet of the passage 25, at the bottom of the mold, for the circulation of the medium upwardly through the core I and its partitions or wings, in order to expedite the setting of the concrete by the heat transfer through the walls of the latter, the medium being exhausted at the outlets or vents 22a at th'e top of the mold.

Without further description, it is believed to be obvious that I have provided a practical embodiment of my invention and that its novel features of construction and arrangement will be -readily comprehended, as will also be its aim to make possible the lessening of the costs involved in the installation of gas and oil pipe lines. While I have described my invention in a preferred embodiment, it is to be understood that th'e words which I have used are words of description rather than of limitation, and that changes within the purview of the appended claims may be made without departing from the true scope and spirit of my invention in its broader aspects.
